What CloudFormation template version to use

There are two basic versions of the MarkLogic CloudFormation Template. One template will launch a MarkLogic cluster on AWS with a new VPC. The other template will launch a MarkLogic cluster in an existing VPC on AWS. Both templates allow you to specify parameter values at startup to configure the cluster.

Both templates enable you to launch clusters with a Classic Load Balancer (CLB) or Application Load Balancer (ALB) based on the Number of Zones, Elastic Block Storage, Auto Scaling Group, and so on. Your cluster can be in either one Availability Zone or three Availability Zones. Multiple nodes can be placed within each Availability Zone.
